Commentary
Charles Cawley: "If Adelais was the mother of all of Comte Lambert's children, she could not have been born later than [930/32]. This is early for her also to have given birth to her son by her second marriage after 978. The date would of course be later if Adelaide was Comte Lambert's second wife, as suggested above. The origin of Adelais has been the subject of much speculation. Settipani has suggested that she was the daughter of Hugues Comte en Bourgogne and his wife Willa von Thurgau. Chaume suggested that Adelais was the daughter or granddaughter of Charles Constantin Comte de Vienne. Bouchard sets out several different theories concerning Adelais's origin, with the aim mainly of explaining Lambert's accession to Chalon by inheritance through his wife. However, none appears to be based on any primary documentation and Bouchard concludes that she prefers "to leave Adelais's origins unknown". An earlier theory was that Adelais was the sister of "Wera" Ctss de Meaux, which would mean that she was Adelais, daughter of Giselbert Duke of Burgundy & his wife Ermengardis [de Dijon]. Duchesne suggested that she was the daughter of Robert Comte de Meaux et de Troyes, although this would mean that the two wives of Geoffroy I Comte d'Anjou were sisters, no mention of which has so far been found in contemporary sources. Another suggestion is that Adelais Ctss de Chalon was the same person as Wera-Adelais Ctss de Meaux. However, this is even more unlikely from a chronological perspective considering the estimated birth date of Wera-Adelais and the fact that Adelais de Chalon gave birth to at least one child by her second husband, Geoffroy Comte d'Anjou, after her marriage in 979. It would also mean that Comte Geoffroy married, as his second wife, his first wife's mother which is unlikely. In 1619, Duchesne suggested that Adelais was the sister of Guillaume I Comte d'Arles."
